Automatic row alignment device of root-tuber crop harvesting machine

Abstract

The invention provides an automatic row alignment device of a root-tuber crop harvesting machine. The automatic row alignment device comprises a tractor, a row alignment mechanism, an excavating mechanism, a land wheel, a hauling mechanism, a piston rod, an oil pump and a rack; when the row alignment mechanism deviates from the center of a crop row, a profiling cylinder is crashed by root caps to move upward along a support frame, and a wedge block moves upward to enable a two-position two-port hand-operated directional vale to reverse; due to change of an oil way, the piston rod is forced to move, and the rack rotates around the hauling mechanism, i.e., the row alignment mechanism and the excavating mechanism move together; during the movement process of the row alignment mechanism, the piston rod is ensured not to move any more under the effect of a spring and the two-position two-port hand-operated directional valve, and the rack does not rotate around the hauling mechanism any more, i.e., the row alignment mechanism and the excavating mechanism do not move any more, and the row alignment operation is finished. The automatic row alignment device can be applied to the root-tuber crop harvesting machine, and is capable of reducing the situations of missed crop excavation and crop damage caused by excavation, and improving the crop harvesting rate.

Description

【Technical field】 [0001] The invention relates to a rowing device, in particular to an automatic rowing device for a rhizome crop harvesting machine. 【Background technique】 [0002] my country is a large agricultural country, and root crops such as potatoes, sugar beets, and carrots are important economic crops in my country. Its planting area, total output, and export volume all rank first in the world, and it is one of the important economic sources of our country. However, the degree of mechanization of tuber crop harvesters is seriously lagging behind, especially in the planting and harvesting links. The amount of labor accounts for more than 2 / 3 of the whole production process, and the operating cost accounts for about 70% of the total production cost. For a long time, due to the constraints of various factors, farmers have been using manual and semi-mechanical harvesting methods for harvesting such crops. The labor intensity is high, the efficiency is low, and the los...

AI Technical Summary

Problems solved by technology

The existing tuber mechanized harvesting equipment is still based on the development and promotion of small and medium-sized potato and peanut excavators, and there are problems such as low technical level, single structure, poor adaptability, and poor quality, which make the harvesting machinery and devices effective. Insufficient supply

The research on the parallel device of the harvesting machinery is still in the stage of trial production and testing, and the research on new structures and new theories is relatively small, which affects the improvement and development of harvesting machinery.
